No offense taken; I hope you understand that I intended no offense either.
Actually, I did know about Tesla Motors. Until their recent move to Menlo Park, they were headquartered about 40 miles from me, so they've been featured in the local news media, plus I'd seen the recent episode of "Supercars" on SPEED Channel, so I was aware of the performance. The torque that electric motors can deliver instantly is the whole reason they're used in locomotives. Put that into a lightweight car and you have the potential for amazing acceleration. I particularly like their anecdote about asking passengers to turn on the radio and then nailing the throttle.
I was also aware that efficiency has been increasing with the advent of the same modern controls that make modern hybrids livable and better battery and motor designs, but I was not aware how
much they had improved. If, in fact, a Tesla can make a trip to the football game and back on one charge, that's pretty amazing and practical for many people. In fact, for 95% of my personal needs, a current-generation electric car would do just fine. (No pun intended) I do wonder about winter, when battery efficiency falls and how much that costs in range. (I suppose anyone that could afford to buy this car, could afford a hotel room or a rental car and a tow truck.) I also doubt that you could get similar numbers out of something the size of a Challenger. If this little roadster, barely larger than the Lotus Elise it shares some parts with, weighs almost 800 lbs more than that same Elise, how much would a relatively large car like a Challenger weigh? If the current car weighs 4000 lbs, could an electric Challenger weigh less than 4500? How will that affect efficiency?
I don't really disagree with you; a livable electric car would be pretty cool and I have no doubt the day is coming. Coupled with the introduction of cleaner power plants - wind, solar, geothermal, hydro (and hopefully someday soon, my favorite, fusion), electric vehicles could prove a big help in weaning humanity from dependence on fossil fuels, with all the attendant problems they create. I'm also a big fan of efficiency - I drive my little UAV as a daily driver not because I can't afford anything better but because I could buy it for next to nothing and drive 80 on the freeway and still get 30 mpg. Sure, it's nothing compared to the power and efficiency of the Tesla, but it only cost me $2100 out the door. I can buy a lot of gas for the $107,000 I save over the price of a Tesla.
OK, so maybe I'm a little cheap.
My point was really more about the practicality of current technology than efficiency or performance. When an all-electric car can be fully recharged in 20 minutes or solar technology gets to the point that you can actually run a car off what can be harvested from the sun
and the costs of owning one are similar to a liquid-fueled vehicle, then electrics will come into their own. Until that day comes, I think the practical disadvantages of electrics will continue to have many cars using some sort of liquid fuel.
